Hemolysis occurs when the thin protective membrane that encloses the fragile red blood cells is ruptured, allowing hemoglobin to escape into the plasma. For example, a purple vial is required for a blood count, and a green vial may be required for a chemical profile. Blood cells are suspended in plasma, which consists of water and dissolved materials, including hormones, antibodies, and enzymes that are transported to tissues, as well as cellular waste products that are transported to the lungs and kidneys.
This less commonly used bottle is intended for biochemical tests that require heparinized plasma or whole blood for analysis.
